As the Xero system seems to encourage you to move from Project to Quote to Invoice it is critical for businesses who partially deliver and invoice quotes to be able to track this. Perhaps an inventory item or service on a quote could be given a status such as 'Filled' and 'Invoiced' so you immediately know at what stage it is at. Partially invoicing a quote at the moment only seems to add the items to the quote instead of eliminating them. Oracle ONLY offers un-invoiced filled items for a new invoice, so you don't invoice an item twice.
